Abstract
Methods and systems are provided for improving catalyst function during an engine cold-start. In one example, at key-off, a duration elapsed till a subsequent key-on is predicted based on drive history and spatial awareness data. Then, based on the duration, an identity and order of operating one or more catalyst heating devices is selected.
